An innovative tissue-retraction material.

One of the most challenging problems of fixed prosthodontics is tissue control. Gingival retraction before a final impression can be very frustrating and time consuming. Many different techniques have been developed over the years to accommodate the clinician's struggle to obtain tissue control and achieve an ideal impression. This article discusses several of those techniques and how the new, innovative product Expa-syl can be incorporated into these techniques. Expa-syl is an injectable retraction and hemostatic agent that can cause little trauma to the tissue as well as save the dentist time and money. The author elaborates on the multiple uses of Expa-syl and the correct techniques for making this material a successful tool in any dental office.
